ISAAC P. WENDELL, OF PHI LADELBHIA, PENNSYLVANIA.

Letters Patent No. 78,704, dated June 9, 1868; antedated May 23, 1868.

IMPROVEMENT IN LUBRIGATING OURNALS 0F GAR-SHAFTS.

tits 5:11am: referrer is in time .itsttm iiitlll mu mating pint if it sane.

Be it known that I, ISAAC P. WENDELL, of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and improved Mode of Lubricating Jour'nals of Gar-Shafts, &c. and I do hereby declare that the following is a full and exact description thereof, reference-being had to be accompanying drawings, and to the letters of reference marked thereon.

The natureof my invention mainly consists in the combination of an air-chamber with an oil-distributing plate and connected tube or tubes, so that the pressure of the air in'said chamber assists the tubes in supplying the journals of cars or other shafts with oil, the chamber being an additional improvement to the mode of lubricating journals, set forth in'my patent, dated January 1, 1867.

In the accompanying drawings, making a part of this specification- Figure 1 is a plan of the improved device.

Figure 2 is a longitudinal section of the same.

Figure 3 is a cross-section at the red line 1-2 of fig. 1.

Figure 4: is a; reverse-plan of the oil-distributing plate -B, supply-tube G, andair-chamber D, detached from the box A.

Figure 5 is an isometrical view of the oil-box A.

Figure 6 is a plan of a modification of the oil-distributing plate B, supply-tube Cyand air-chamber D, arranged in relation to the retaining-plate F.

Figure 7 is a cross-section of the same. A

Figure 8 is a side elevation of the said modification, when used without the retaining-plate F.

.Figure 9 is a cross section of the same..

Like letters in all the figures indicate the same parts.

z A is an oil-box, which I place in an ordinary car-box. It has a horizontal plate, a, beneath which is an oil-chamber, b. B is an oil-distributing plate, the curved surface, a, of which is of the same radius, or nearly so, as that of the journal which it supplies with oil. From the under side of the plate projects a tube, 0, for conveying oil to the curved surface e, as hereinafter described. The tube is surrounded by anair-chamber, D, which projects through the opening d in the plate a of the oil-box A, far enough to cause its lower edges to be always immersed in the oil contained in the chamber 1). The under side of the plateB is provided with springs, E, whose resilient parts rest upon the plate a, as seen in figs. 2 and 3, so as to 'keep the curvedface, c, of the former plate, always gently touching the journal to keep up a constant supply of oil. The plate B is provided with inclines e e, running-fromits curved surface, a, to carry off the surplus oil, there being'vertical openings,- jf, in the plate, through which theoil'descends back into the box A. Abovethe inclines e a there areinclines pg, which are auxiliary to the former.

The operation is as follows:

As the journal revolves, it creates a suction up the supply-tube G, causing the oil to ascend, and the air in the air-cbamber D, pressing upon the surface of the o'il,in the-chamber 6, assists the flow of oil up the tube to the distributing-plate B. The curved surface, a, of the plate being in contact with the journal, distributes the oil evenly thereon, as the latter revolves. The oil which is not carried around .with the journal runs down the inclines c ,e, and through'the vertical openings, ff, back into the oil-box A. The excess of oil that remains on the journal is removed by the scraping-edges it h of the inclines g g, in the following manner: lfthejournal runs in the direction of the arrow, the oil will be scraped-downwards by the scraper h, and upon the incline e beneath it, -and fall through the openings ff and into the oil-chamber b, and as the journal in its revolutions passes the scraper it, the surplus oil which may not have been scraped oil by the scraper h is removed, and runs down the incline g into the oil-chamber 6. Thus a constant supply of oil is kept up to the journal, and the excess removed therefrom, so as to keep its surface clean. The inclines g g are arranged alike in relation to the inclines-e e, so that the journal may run either way, and their action will be the some; i

modification o f the device is shown in figs. 6 and 7, in which'arrangenient an ordinary oil box'is used instead of the box A. The oil-distributing plate B is kept up against the journal by means of the cylindrical spring G, in the circular air-chamber D, the springresting upon the upper surface of the bottom of the box. The distributing-plate B is' retained in its horizontal position each way by means of the plate F, which has an opening, 7', to rcceive-thaair-chamber D. The plate F has flanges, k k, whichrest-vupon the upper surface of the bottom of theoil-box. V I I 1 v Figs, Sand 9 represent another'modification of the device, the plate B being dispensed with. In this arrangement the oil-distributing plate B may be retained in its horizontal position by-having a loose fit in the oil-box. The spring G may be usedeither inside or outside of the air-chamber D.

The combination of a spring or springs withthe oil-distributing plate for hearing it up againstthe journal is essentially the same asset forth in my patent,.dated October 16, 1866, varying only in detail. The flanges 1k, in both modifications, also prevent the surging of the oil.

What I claim asmy invention, and desire to secure by Letters Patent, is 1. The comhination of'theair-ehamber Devith the oil-distributing plate B and supply-tubeC, arranged in the oil-box A, or other oil reservoir, substantially in the manner above described, and for the purpose set forth.

2. The box' A,"having a division-plate, a; andoil-chaniber b beneath it, in combination with the distributingplate B, substantially as described and for the purposes specified.

3'. The construction of the distributing-plate B, with inclines and scrapers, substantially as described and.

for the purpose set forth. v

In testimony that the above is my invention, '1 have hereunto set my hand and afli'xed my soul, this twentysecond day of July, 1867.
